UN METODO DE TRANZA A LONGITUD UN TUBO DE PARED DELGADA.

摘要

Method and apparatus for severing thin walled tubing into selected lengths wherein the method includes circumferentially scoring the outside of the tubing at a predetermined point to produce a narrow weakened portion therearound and subsequently supporting the tubing internally while applying separating forces to the inside of the tubing at the weakened portion to sever the tubing at the weakened portion. The apparatus includes means for selectively measuring the length of the tubing to be severed and means for supporting the tubing internally while applying separation forces to the inside thereof at a circumferentially extending weakened portion to cause the same to sever at the weakened portion. The apparatus also includes means for producing a circumferentially extending weakened portion in the tubing.
